Benefits of technology

The patent text describes a receptacle cage assembly for a communication system. The assembly includes a receptacle cage with cage walls that form a module channel for receiving a pluggable module. The cage is designed to be received in a panel opening of a panel. The assembly also includes a gasket at the front end of the cage with EMI springs that are connected to the cage and the panel. The EMI springs have a deflectable portion that is spaced apart from the cage walls and is deflectable towards the cage walls. The receptacle cage assembly provides improved electromagnetic interference (EMI) protection for the pluggable module.

Problems solved by technology

However, conventional communication systems have performance problems, particularly when transmitting at high data rates.

Embodiment Construction

[0018]FIG. 1 is a front perspective view of a communication system 100 formed in accordance with an exemplary embodiment. FIG. 2 is a rear perspective view of the communication system 100 formed in accordance with an exemplary embodiment. The communication system 100 includes a circuit board 102 and a receptacle connector assembly 104 mounted to the circuit board 102. A pluggable module 106 (shown in FIG. 3) is configured to be electrically connected to the receptacle connector assembly 104. The pluggable module 106 is electrically connected to the circuit board 102 through the receptacle connector assembly 104.

[0019]In an exemplary embodiment, the receptacle connector assembly 104 includes a receptacle cage assembly 108 and a communication connector 112 (shown in phantom) adjacent the receptacle cage assembly 108. For example, in the illustrated embodiment, the communication connector 112 is received in the receptacle cage assembly 108. In other various embodiments, the communicati...

Abstract

A receptacle cage assembly includes a receptacle cage having first and second side walls extending from a top wall at first and second corners. A gasket has EMI springs electrically connected to the receptacle cage and a panel in a panel opening including top EMI springs and first and second side EMI springs. A first corner EMI spring is located outward of the first corner of the receptacle cage to engage the panel at a first corner of the panel opening. A second corner EMI spring is located outward of the second corner of the receptacle cage to engage the panel at a second corner of the panel opening.

Description

BACKGROUND OF THE INVENTION[0001]The subject matter herein relates generally to receptacle cages.[0002]Some communication systems utilize receptacle assemblies having communication connectors to interconnect various components of the system for data communication. The receptacle assemblies include receptacle cages that receive pluggable modules, such as I / O modules, that are electrically connected to the communication connector. The receptacle cages provide electrical shielding, such as EMI shielding, for the pluggable modules. The receptacle cages are typically arranged at an interface of another component, such as through an opening in a panel or bezel. Conventional receptacle cages have gaskets at the interface with the panel to electrically connect the receptacle cage to the panel. However, conventional communication systems have performance problems, particularly when transmitting at high data rates. For instance, gaskets of known communication systems are leakage areas for EMI...
